A number of plain weave silk-like polyester fabrics with different surface texture were collected, data of fabric structural parameters were analyzed, and surface texture characteristics were tested. According to the relationship between structural parameters data and surface texture characteristic value, firmness and weft twist factor were found to be the main factors that affect the surface texture of single direction crepe. Finally, let tightness and weft twist multiplier be contributing factors, surface texture characteristics of single direction crepes were obtained by data analysis and regression equations.

Abstract: This study is an attempt to optimize the parameters for the neckline of children’s T-shirts. Experiments are made with six different kinds of knitted fabrics to analyse the relationships between fabric performance, sewing conditions and the neckline elongation of T-shirts. The result shows that there is a high correlation between course density, wale density, linear density, and T-shirt neckline. A multivariate regression analysis results in the establishment of a mathematical model, through which the neckline elongation can be obtained without sample trials so that the parameters for children’s T-shirt neckline are optimized and the design process simplified.

Abstract: Tencel fabrics were treated with low pressure plasma with air for different treatment time. The samples were tested their thickness and calculated each mean value of fabrics treated with different time. The result indicated that samples became thicker with the prolonged plasma treatment time. The samples were also divided into two groups and tore along warp and weft direction, respectively, to measure the influence of plasma treatment time on the tearing strength. The result of the measurement implied that the tearing strength of samples treated 1 minute by plasma decreased dramatically, when they were compared with the untreated ones. However, the decrease of the tearing strength became slight when the plasma treatment increased to 5, 10 and 20 minutes.

Abstract: Cotton fabrics are very popular textile products to consumers due to their soft hand and comfortable wearing performance. However, the severe wrinkles on cotton fabrics will frequently happen after washing or wearing. As the growth of the market and demand of consumers, the sales of the steam ironing machine which can remove wrinkles to some extent is getting better. At present, the research is inadequate on the wrinkling mechanism during steam ironing. Therefore, in this paper, we aimed to investigate how cotton woven fabrics’ performance influences on the smoothness appearance after steam ironing. To further analyze wrinkling mechanism, fabrics’ wrinkle recovery rates which comprehensive characterize the physical and mechanical properties were tested with PhabrOmeter, including wrinkle recovery rates at normal temperature and after high temperature treatment. Then, the effect of temperature to fabrics’ wrinkle recovery rates and its relationship with fabrics’ smoothness appearance after ironing were studied. The results indicate that there are no significant correlations between the fabric basic parameters with smoothness appearance after ironing. The effect of temperature during ironing can improve the wrinkle recovery rates about 6%-21%. And no significant correlation is showed between smoothness appearance after ironing and wrinkle recovery rates.
